Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed September 1, 1920. Serial No. 407,441.

To all whom it may concern:

Be it known that I, ZYGMUNT SLAWINsKr, a citizen of Poland, residing at South Plainfield, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Rail-Ties, of which the following is a specification.

The main object of this invention is to provide a quick-detachable railroad tie, which may be quickly opened so as to allow removal of a broken or otherwise injured rail, and quick replacement of the same by a new rail, thus eliminating delay to traffic.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a perspective view illustrating the application of my device.

Fig. 2 is a cross-sectional view taken on the plane 2-2 of Fig. 3;

Fig. 3 is a plan view of my device.

Fig. 4; is a cross-sectional view taken on the plane 1- 1- of Fig. 3.

Fig. 5 is a side elevational view of the same, in open position.

Fig. 6 is a plan view of a modified form of my device.

Fig. 7 is a side elevational view of the same, showing the mechanism in heavy lines and the tie base in dotted lines.

Fig. 8 is a plan view of the same with the cover removed.

Referring now in detail to the drawings,

the numeral 1 represents the base of my tie having a recess 6 at the top thereof, and be ing covered by a panel5. Two sections of a rail 2 joined by a rail joint 3 are shown (Fig. 1) clamped between the stationary jaw 4; and the movable jaw 7. A bar 8 is at tached to the jaw 7 and situated under the panel 5, said bar and jaw being joined by screws and nuts 9 passing through a slot 9 in the panel 5. A link 10 is attached pivotally at one end to the bar 8 and at the other to a lug 10 projecting from, and rigid with, a short shaft 11. A lever 12 having a hook 13 on its outer end is rigid with the shaft 11 and adapted to turn the same. A slot 14 is provided in the panel 5, through which the hook 13 passes. A boss 15 is slidable on the panel 5, the same being rigid with a plate 15 mounted underneath the panel 5, and parallel therewith. A screw and nut 30, passing through a slot 31 in the panel 5, binds said boss rigidly with said plate. A slot 14 of the same dimensions as the slot 14, is provided in the plate 15 the boss15 being slidable so as to move said slot 14 into registration with the slot 14, thus allowing the hook 13 to pass through, in succession, the slots 14 and 14 Itis apparent that, with the hook in position in said slots, the boss 15 may be moved back so that the plate 15 will engage the hook 13 and thereby prevent withdrawal of the latter, and hence of the lever 12.

It is now apparent that, when the lever 12- is rotated in a counterclockwise direction, the jaw 7 will be forced against the rail 2, thereby locking the rail between the jaws 7 and 4. The lever having been moved as far as possible in said direction, the boss 15 is then moved as above-mentioned, locking'the hook 13 and lever 12 in closed position. In order to insure locking of the clamp, I have provided a tension spring 19 surrounding a rod 20, the latter being slidable in a sleeve 21 rigid with the plate 15*. The other end of the rod is rigid with the panel 5. Thus the spring 19 urges the boss 15 to the left (Fig. 2) so as to prevent withdrawal of the hook 13.

In the modified form shown in Figs. 6, 7, and 8, the jaw 7 is attached by a screw and nut 32 to a plate 33 having a slot 22 therein, said plate lying under the panel 5 and parallel thereto. A recess 23 is provided in said plate, adapted to be engaged by a hook 26 on a pivotally and slidably mounted finger 2 1 controlled by a slot 25. A spring band 27 pivoted at 28, urges said hook 26 against a shoulder 34 of the plate 33 so as to keep the clamp closed. When the clamp is open, the same spring urges said hook into the recess 23, thus keeping the clamp open until again closed by removing said hook from said recess A spring 29 normally urges the base, a panel mounted over said recess, slots in said panel, a stationary aw, a slidable 121W, a lever pivot-ally mounted 1n sald base,

; links connecting said slidable jaw with said side of saidpanel, an additional slot in said panel through which said hook is adapted to pass, said plate being adapted to engage said 10 hook, and resilient means normally urging said plate into'position to engage said hook. In testimony whereof I affix my signature.
